aabbTransform :: Mat44 Float -> AABB -> AABBSource

Transforms an 'AABB* using a 4x4 matrix. Note that this may grow the AABB and is not associative with matrix multiplication, i.e. 

 (m2 `multmm` m1) `aabbTransform` aabb

is usually not the same as 

 m2 `aabbTransform` (m1 `aabbTransform` aabb)

(The former is preferred as it minimizes the growing of the AABB).

testAABBprojection :: Mat44 Float -> AABB -> IntersectionSource
Try if an AABB is inside a projection frustum. The AABB must be defined in the same vector space as the matrix, e.g. use the model-view-projection matrix for model-local aabb's.
